To mi finden?, imag concern lds it that l, Coeur Yorin, citizen the States. residing et Memphis, jf E d. (5;. .if l the ce y or Shelley end @este or llenessee. have invented eert-einnew and useiinprovernents in .implements for Melring iheinliinlrs, oit which the following is e. specification.

` seid invention relates to an implement to he used in the manufacture of lrols for. melting chains which are :adapted rer use in various relations but are psrticnlerly intended for use'in melting armor for autom-chile tires out of used tires. it is object of my invention to provide a; simple and eective implement which shall torni e. complete chain linkv in a single operation.

further object of the invention is to provide means in connection With the link he ig deviceto ect e gege for determin- "ug 'the length ot the Wire to ne used in malrlinl.

Referring to 'the accompanying drawings which ere mede e. part hereof end on which iler reference characters indicate similar ginre is a pien View of the implement to begin the operation of forining e linl A Figure is e similar view showing the position assumed by the parts in making the first bend in the Wire.

Figure -3 is e. section on line 3 3 ure 2, and

igure el shows 'the completed link.

the drawings reference character 5 indicates the heee of the implement which may l'" attached to any convenient support by u' conventional means such es screws 6. Upon 'ease o are :t pair of vertical pivots 7 each of Which'carries a lever 8 adapted to oscillate in a horizontal plane if the bese be assumedto be xed in a horizontal 'position. lt will he evident that the position of the hase may be varied Without untoward results. For exemple, it may be attached to e. vertical Well if desired. Each or'. the levers 8 has a. recess 9 near the pivot andan inclined projection 10. A boss 11 extending upwardly from the base is adapted to heer against the ends of levers 8 and thus limit their outward movement.

in front of hess 11 is e bending niemeer of Fig- .ngiiieeton :'llefl april 27, 192i.

'shown in Figure 1'.

V.form ot the them Will tend to hold Serial No. ve-Ses.

12 about which the iirst bending operation talces place. This member has a laterally enlarged portion 13 adjacent the boss 11 and o similar altitude forming ay stop to limit the movementof e vertically swingable lever 1s which when in cout-ect With the stop assuines lthe position indicated in dotted lines 1n Figure 3. ln rear ofthe, stop 13 the former 12 has e vertically extending fin 15 in which is formed e slot 16 for the pin 17 `which :acts es a pivot lor the lever 14. rhis lever is formed et its end to rest against the base 5 and has a lip 18 extending beneath the bese and adapted to rest against a supportsuch es indicated at 19. The tin has also e slot 10" to receive the inclined lugs '10 on levers S.

ln the operation oi' the suitable Weight is cut into shown at in Figure 1. The base 5 may be used es e gage in this connection, its longest dimension being the seine as the length of Wire necessary to forniv zi link such as have found most desirable in practice. This Wire is placed between part 11 and 13 and under the lugs 10 on levers 8 in the position Then the arms are direction of the erdevice a, wire of lengths such as moved forward in the rows to the position shown in Figure 2, the Wire being bent es indicated, and the lugs 10 entering slot 10it the thickness of the Wire permits. The lever 14 isthen moved in the direction of the arrow (Figure 3) to the dotted line position. sliding fulcrum in slot 16, and so at first moves pivotallyuntil the body of the lever at the end of the crotch bears against the edge of the iin, after which the lever slides on the fin and continues to swingen its fulcrum until it reaches the dotted line position7 bending the ends 21 of the Wire as shown in Figure el. Jlhe levers 8 are 'held by hand in the position shown in Figure 2,if necessary. The structure shown is intended to render this practically unnecessafr3y as the parts and the friction between them in the positionl of Figure 2. rEhe lugs 10 slope toward the front of the implement so as to hold the ends of the Wire close to the fin 15 during the bending operation and the arm 14 thus .acts through the Wire and the lugs 10 to assist in holding the arms 8 in position. In addition to this the lugs 10 hy their engagement The lever has a under the upper face of the slot 10 hold the levers 8, 8 down and prevent lever 14e from exerting a bending action on their pivots 7, 7. When the movement of lever 14 to the dotted line position in Figure 3 has been completed a link is finished as shown in Figure 4. In the operation of the lever 14; the wire rests on its upper flat tace and the lpin and slot connection at 16, 17 permits an easy rolling movement of the lever by Iwhich it comes to rest with its normally upper face on the lat faces of the closed levers 8, 8, which act as anvils to receive the blow of lever 14, and the ends oi' the wire are bent'over the lugs 10 so as to leave them in proper relation for joining with other links. In use for making suchtire armor as described the sides of the link slip on the neck just above the bead of'a piece cut crosswise from a tire shoe, and the hooked parts engage the loop of the next link. A similar chain is formed at each side of the armor and in this manner a very effective armor may be made from old tires at little expense. v

A succession of links may then be strung together as will be evident and in carrying out my particular purpose a tire ot ordinary form will be cut into lengths to t loosely within the links and will be inserted into the chain as formed with each bead of the tire section at the under side of a linkoi one of the two chains which, together with the segments of the tire form an armor such as may begplaced about a pneumatic tire in use on an automobile or other vehicle.

It is to be understood the terms horizon tal and vertical are used. in the claims to indicate movement in the pla-ne of the base and in a plane at right angles thereto respectively. As hereinbelore explained the position of lthe base and attached parts is immaterial and these terms are used merely for description and not for limitation.

Having thus fully described my said invention, what I claim new and desire to secure by Letters Patent, is:

An implement Jfor forming chain links comprising a base, a pair of levers mounted thereon for horizontal movement, a. boss 'between the ends of said levers to limit their rearward movement, a former on the base having a head and a fin, said tin having an arcuate, substantially vertical slot, a third lever having a pin in the slot and horizontally extending lugs on the first levers about which the third lever may form a second bend in the link after the same has been bent 'a base, a former on the base having a laterally enlarged head and a vertically extending fin, a horizontal slot in the fin, 'a pair of horizontally movable arms on the base a base, a fixed former thereon, a pair of arms i mounted for horizontal movement on the base to bend a wire about the former, an arm pivoted to the former having its upper face adjacent the base normally in the plane of the base and adapted to contact with the ends of a Wire lying on the base and to impartf'" i a second bend to the wire after the same has been bent by the first pair of arms, sub- 3,9
